Use this contactor from Siemens to ensure your load feeder doesn't overwhelm your operating units. It takes reliable control of your power supply by switching an electrical circuit on and off. This gives you the upper hand in energy consumption by cutting back on power wastage and also protects equipment from the damaging effects of voltage surges. To maximise board packing efficiency, the unit has compact dimensions of 58 (H) x 45 (W) x 117mm (D). It comes with four built-in auxiliary contacts, giving you further space-saving benefits. This is the ideal controller for devices that distribute energy from a mains power source to low-voltage circuits, such as motor starters used in lighting systems.

• Broad operating temperature range between -25°C and +60°C for use in demanding conditions
• Screw terminals simplify wiring and hold conductors securely to reduce the need for maintenance
• IP20-rated front panel is touch-proof to protect you against electric shocks
• Delivers up to 10 million mechanical operating cycles, so keeps pace with high-turnover setups

This contactor has a power rating of 5.5kW, so it's a high-performing option.
